Mouth ulcers concerns

Mouth ulcers are painful sores that appear in the mouth, usually on the soft tissue - cheeks, lips or tongue. They can be white, red, yellow or grey in colour and swollen.

Although they're uncomfortable, mouth ulcers are usually harmless and clear up by themselves within a week or two.

In many cases, the reason for mouth ulcers is unclear, but triggers are thought to include:

  • Accidentally biting the inside of your cheek or a sharp tooth
  • Poorly fitting dentures
  • Hard food
  • A defective filling
  • Stress and anxiety
  • Hormonal changes – some women develop mouth ulcers during their monthly period
  • Eating certain foods – such as chocolate, spicy foods, coffee, peanuts, almonds, strawberries, cheese, tomatoes and wheat flour
  • Toothpaste containing sodium lauryl sulphate
  • Stopping smoking – when you first stop smoking, you may develop mouth ulcers
  • Viral infections – including the cold sore virus, chickenpox, and hand, foot and mouth disease
  • Medical conditions - including vitamin B12 or iron deficiency, Crohn's disease, coeliac disease, reactive arthritis, HIV, lupus, Behçet’s disease
  • Certain medications or medical treatments may also cause mouth ulcers

It's usually safe to treat mouth ulcers at home to help reduce swelling and ease any discomfort.

Self care

Tips for easing discomfort and aid healin…

  • Antimicrobial mouthwash or protective paste, available from your pharmacist
  • Use a soft toothbrush to brush your teeth
  • Use a toothpaste that doesn’t contain sodium lauryl sulphate, as this may be irritating
  • Avoid hard, spicy, salty, acidic or hot food and drink until the ulcer heals
  • Use a straw to drink cool drinks
  • Avoid things that may be triggering your mouth ulcers

Mouth ulcers can sometimes be a possible symptom of a more serious problem such as infection or mouth cancer. It's therefore essential that you contact [practice name] as soon as possible if you notice:

  • your mouth ulcer has lasted three or more weeks
  • you keep getting mouth ulcers
  • your mouth ulcer becomes more painful or red

Great Dentist. Ranya is very professional. She considers the problem and finds the best solution. She is very gentle and meticulous. I highly recommend her.

This was an emergency appointment with Amit Gadhavi to alleviate severe tooth ache. He examined, discussed the options, removed the filling, cleaned the root canal and applied a temporary cap. The treatment was uncomfortable but not painful (he saw to that immediately). He explained the options and has referred me to his recommended specialist for the root canal treatment. I have complete faith in Amit.

Clare Wood is the reason I keep returning to Mortiboys. She is the most fabulous hygienist and has prevented any dental issues I may have developed. Clare Wood is outstanding.

Amit and Caron have been absolutely brilliant at helping with my gum disease. They are kind, gentle and very knowledgeable, taking my complex medical history into account and explaining everything in detail. I used to be nervous of going to the dentist, not anymore though. Everyone at Mortiboys has been brilliant, no exceptions, thank you so much.
